Isabel Swift is a hard-nosed, down-to-earth, female police officer who protects the citizens of Westchester County and wants to become a detective. From a broken home, her brothers and sisters in blue are her family, and she is shaken by the recent, unexpected death of her mentor, Ben Carter, from what everyone thinks was a heart attack. On her first day back from leave, she is paired with an arrogant forensic data scientist, Mark Jameson, who is more interested in data analysis than solving the crime of stolen technology and murder to which they are assigned. In 72 hours, Izzy Swift must overcome her differences with her new partner, whittle down a county-wide list of suspects, and track down the stolen technology. With her career on the line, can she find the thief, solve the mystery of the death of her mentor, and earn her detective's badge?
